Assistive Touch

I have someone using a Verizon iPhone Version 5.0.1 (9A405) On the screen this person has this "White Dot" that once pressed opens up a menu.  I would like to disable or turn off this "APP"  I can't figure out how to do it.  I looked under the "General Settings" and there was no toggle switch to turn it off like in other videos I have watched.  I called the Apple Help desk who told me they think the phone was jailbroken but I don't think this person did that.
So who can help me?  I posted 2 pictures below. Thanks

Update: OK so this is called Assistive Touch. 2 ways to turn this off:

1) Go to Settings

     Assistive Touch

     Turn Off

2) Select the "Dot"

     Go to "Gestures" 

     Choose a Gesture Square

     Assistive Touch Off
